The visual image process begins with the entry of light to (1) EYEBALL
(2)LUMINOUS RAYS come from the observed object
The luminous rays are focused by the (3) CORNEA
The luminous rays then cross the (4) AQUEOUS HUMOR
The luminous rays converge in the (5) LENS
Then, are projected through the (6) VITREOUS HUMOR to the retina, structure where the observed image is focused
The contraction and dilation of the (7) IRIS MUSCLES allows the regulation of the pupil
The (8) PUPIL setting helps to maintain a proper exposure the retina to the light.
To accommodate the len, enable the luminous rays are projected on the (9) RETINA
The (10) FOCUSED PICTURE on the retina is inverted.
The nerve messages leave the retina by the (11) OPTIC NERVE
The visual information received by the retina is processed by the (12) LATERAL GENICULATE NUCLEUS
Finally, visual information reaches the (13) AREA OCCIPITAL of the cerebral cortex where they are processed and analyzed.
